I use an Epson R220, R1400 and a big (44") Epson Pro Stylus 7600. I put in an outside waste dump for the R220 and have a little program that resets that counter. I have a similar program for the R1400, but have not yet installed the waste dump. (just leading the waste ink tube outside the printer into a bottle and sealing it.) Both printers are programmed to shut down after a certain number of prints, because by then the waste tanks inside would be full, and further ink from cleaning cycles could start affecting electronic connections. The reset programs are useful if you install an outside dump.
